TString: Manipulate string values

This class can be used to manipulate string values.

It encapsulates several types of operations that manipulate string values by the means of a fluent interface.

Currently it can concatenate an array of strings, change the case of the string words, split the string in pieces separated by another given string, find a given sub-string, pad the string with characters to fill a given length, extract a sub-string. insert a sub-string in a given position. replace sub-strings, trim the string, etc..
