Subject: Add Platal::assert() function
X-Git-Tag: core/1.1.0~72
X-Git-Url: http://git.polytechnique.org/?a=commitdiff_plain;h=ec60dba7a82f71656896e0ea3acb4b74eafbb15c;p=platal.git

Add Platal::assert() function

Used to put assertion in the code.
If an assertion fails, a message is written to spool/tmp/assert_errors,
   and another one is shown to the user
