 /// @notice
-///         Binary trees
+///         This library provides utilities for manipulating, and verifying proofs about, a kind of
+///         merkle tree accumulator.
+///
 ///         --------------------------------------------------------------------------------------------
-///         A complete tree is a balanced binary tree - each node has two children except the leaf
-///         Leaves have no children, they are a complete tree of size one
-///         Any tree (can be incomplete) can be represented as a collection of complete sub trees.
-///         Since the tree is binary only one or zero complete tree at each level is enough to define any size of tree.
-///         The root of a tree (incomplete or otherwise) is defined as the cumulative hashing of all of the
-///         roots of each of it's complete and empty subtrees.
+///         The accumulator is composed of a number of complete merkle trees.
+///         A complete tree is a tree with a leaf size of a power of 2
+///         One or zero complete trees at each power of 2 is enough to define any size of accumulator.
+///         The root of the accumulator is defined as the cumulative hashing of all of the
+///         roots of each of its complete trees, substituting a zero where no tree is necessary at that power of 2
+///         Where we refer to "level" in this documentation we mean the power of 2 used at the level: 2^level
+///         Where we refer to a subtree we mean one of the complete trees which makes up the accumulator.
 ///         ---------
-///         eg. Below a tree of size 3 is represented as the composition of 2 complete subtrees, one of size
-///         2 (AB) and one of size one (C).
+///         eg. Below are 3 leaves (A, B, C) which can be represented as an accumulator made up of the
+///         composition of 2 complete subtrees, one of level=1: 2^1=2 (AB) and one of level=0: 2^0=1 (C).

 ///         --------------------------------------------------------------------------------------------
-///         The minimal amount of information we need to keep in order to compute the root of a tree
-///         is the roots of each of its sub trees, and the levels of each of those trees
-///         A "merkle expansion" (ME) is this information - it is a vector of roots of each complete subtree,

+///         is the roots of each of its complete subtrees, and the levels of each of those subtrees
+///         A "merkle expansion" (ME) is a representation of this information - it is a vector of roots of each complete subtree,
 ///         the level of the tree being the index in the vector, the subtree root being the value.
-///         The root is calculated by hashing each of the levels of the subtree together, adding zero hashes
+///         The accumulator root is calculated by hashing each of the levels of the subtree together, adding zero hashes
 ///         where relevant to make a balanced tree.
 ///         ---------
 ///
-///         ME Example 1
+///         ME Example 1 - 1 leaf C
 ///
 ///         C => (C)
 ///
-///         ME of the C tree = (C), root=(C)
-///         The merkle expansion of a tree consisting of a single leaf is vector of size one with the
+///         ME of the C tree = (C), accumulator=(C)
+///         The merkle expansion of an accumulator consisting of a single leaf is vector of size one with the
 ///         zeroth index being the leaf C. The zeroth index of the vector represents the presence of a size
-///         one complete subtree in the overall tree. So if a tree has a size one complete subtree as part
-///         of its composition, the root of that size one tree will be present in the zeroth index.
+///         one complete subtree in the accumulator. So if an accumulator has a size one complete subtree as part
+///         of its composition, the root of that size one accumulator will be present in the zeroth index.
 ///
-///         ME Example 2
+///         ME Example 2 - 2 leaves A and B
 ///
 ///            AB
 ///           /  \
 ///          A    B
 ///
-///         ME of the AB tree = (0, AB), root=AB
-///         The merkle expansion of a tree consisting of a single size 2 complete subtree is a vector
+///         ME of the AB tree = (0, AB), accumulator=AB
+///         The merkle expansion of an accumulator consisting of a single size 2 complete subtree is a vector
 ///         of size 2, with the zeroth index value being 0, and the 1st index value being the root of the size
-///         2 subtree. The zero in the zeroth index indicated that there is not a size 1 subtree in the tree's
-///         composition. If a tree has a size 2 subtree in its composition its root will be present in the
+///         2 subtree. The zero in the zeroth index indicated that there is not a size 1 subtree in the accumulators's
+///         composition. If an accumulator has a size 2 subtree in its composition the root of the subtree will be present in the
 ///         1st index.

 ///           /  \
 ///          A    B    C
 ///
-///         ME of the composed ABC tree = (C, AB), root=hash(AB, hash(C, 0)).
-///         When a tree is not itself a complete subtree, but rather a composition, zeros are added when
-///         calculating the root. To do this hash the first complete sub tree with zero, and from there
-///         cumulatively hash the merkle expansion.
+///         ME of the composed ABC tree = (C, AB), accumulator=hash(AB, hash(C, 0)).
+///         When a accumulator size is not a power of 2, a composition of subtrees is used to calculate it's value.
+///         The lowest level sub tree is hashed with zero, to form the initial accumulator. The accumulator is then
+///         hashed with the value (including zeros) at each level of the expansion.
 ///         The merkle expansion of this composed tree is a vector of size two. Since it has a size one tree in
-///         its composition the root of that goes in the zeroth index of the expansion - C, and since it has a
+///         its composition, the root of which goes in the zeroth index of the expansion - C, and since it has a
