Add support for regex in classes list

[SainathSharmadha]

If package list is :
org.apache.abc.def
org.apache.xyz

and classes list is given as :
org.apache.xyz.class1

tool doesn't scan all classes under org.apache.abc.def. To make it work , if I try

package list:
org.apache.abc.def
org.apache.xyz

classes list is:
org.apache.xyz.class1
org.apache.abc.def.*

tool doesn't recogonize org.apache.abc.def.* as it looks for exact match and not regex. Since list of classes under org.apache.abc.def are huge , specifying all classes is a pain
