libplis 0.1.4

libplis is library for Perl-like string manipulation for C++. It includes the string class plis::slip and the list class plis::llip.
Together, these two provide the Perl-like methods that include regular expressions (through PCRE), split(), join(), grep(), chomp, tr///, s///, sprintf(), etc.
It can also be described as a C++ frontend to PCRE, but its array manipulations make it much more powerful than only that. libplis library comes with Doxygen API documentation.
Enhancements:
- A few new utility functions have been added (slip_read_file and slipvprintf), a memory leak has been fixed, and a few problems in the documentation have been fixed.
