This implementation fixes major limitations known and reported for years.
It can be used in Scilab >=5.5.0 on Windows, Linux and Mac OS.
FEATURES ADDED W.R.T. SCILAB NATIVE VERSION
-------------------------------------------
- in regular expression mode, all occurrences are replaced: fixes the bug 4276
- a 'ro' flag is added to still enable replacing only once in regexp mode.
- group replacement is supported: fixes the bug 9123
- multiple Pattern/Replace pairs can be replaced: fixes the bug 6145
- hypermatrix of text is accepted
- examples run with strsubt() are added
These extensions are fully compatible with the existing strsubst().
