boolparser

This package defines a simple boolean parser using PyParsing that allows user defined variables and floating point numbers to be used in a nested boolean comparison. For example, if the variables a,b, and c are defined then the following string can be parsed

(a==1 & b<2) | c>4

The resolution of a, b, and c is left up to the user by inheriting from the class EvaluateVariable class and overriding the eval function. This allows the variables to be references to (say) data stored in a file.
