Added missing line (parser conversion).
Use ENDNUM and prepare for IMBNUM.
Make use of keywords SATOPTS and EHYSTR.
Reset gwseg as the model for endpoint scaling.
ENDNUM: changed default value and jtab-logic

Default value changed from 'no scaling' to 'use table 1'.
Range of jtab changed to [-1,#tables-1].
Fix to make EQLNUM consistent with ACTNUM.

This should eventually be integrated in the parser.
Inserted some documentation.
Initialisation of EGLNUM (analogous to e.g SATNUM)
Proper interpretation of ENDNUM and IMBNUM fields.

Made consistent with grid discretization.
Removing a few bugs ...

Add OnlyWater as a special case in the class PhasePresence
The case where there is only water present is represented
here as well, as this case needs special attention.
