Hydro Model changes

Using kcfs and Acre-ft units.  Compute initial power from initial
outflow and volume.  Commented out two var PWL because I couldn't get it
to work right.  Using Linear curves at this point.  Computing volume
balance using change in volume from last hour.  Added ramping and
net_outflow constraints.  Added penalty for spill.
Changed hydro input data to static values

time varying limits not working right now.  Removed "elevation" and
"power" initial values from hydro initial input file, these are
dependent on volume and head calcalutions.  Let model compute them.
Adding Penalty variable to optimization function

Need penalties to differentiate and prioritize been two similarly
variables that don't have costs associated with them.  Hydro_var panel
not concat'ing correctly.
Changes solution time formatting

cosmetic
Added Penalty logic

partial implementation for non-hydro generation.  Expect to add a
ramping penalty and a dump energy penalty
Added Penalty logic

Added penalty logic and cosmetic change to object names.  Names are
currently mandatory.
