PgEntity parser fromPg now supports empty fields (#19)

    The preg_split expression appears not to be able to handle complex
    CSV output like it is in Pg. It has been replaced with the dedicated
    "str_getcsv" PHP function. This should also allow wider field length
    (binary content by example).
Map generation problem with user defined types. (#18)

    Types defined in schemas were not handled as arrays during the map
    generation.
VERSION 1.0.2
changed version to 1.0.3-dev
PgArray uses str_getcsv

    This fixes an important performances issue with arrays.
    Thus, the previous preg_split used to segfault when the data
    were too large (> 8kb).
Generation using inheritance was broken.
PgEntity returned entities marked as existing.
VERSION 1.0.3
Changed version to 1.0.4-dev
Deleted old tests, added Where.
Added tests for BaseObject.
BaseObjectMapTest
Bug in Collection and tests.
PgEntity factorization #30

    PgEntity now takes a map instance as parameter for its constructor.
    This allows to give modified Map instances with extra virtual
    fields (and extra fields).

Anonymous queries now from Connection

    When made from Database instance, executeAnonymousQuery was creating
    a new connection every time which messed up with the transaction
    system. This means the transaction system was not tested and needs
    to be.
