give a value the Modulation_internal to avoid the error when avoidEvents = false + add scaling factor to the internal mass of HP and to its m_flow_nominal. This is necessary to linearly scale the pressure losses with the scaling factor.
Deleted obsolete pseudo-package IDEAS/Media/Air.mo
Two simple hysteris controllers with variable uLow and uHigh and release for heating and cooling
Example and unittest for heatpump air-water (#47)
Heatpump AW now allows events, but this does NOT slow the model down, specifically not with LSODAR (#47)
add an on/off switch to Pump.mo
correct unit of riseTime in PartialHeatPump.mo, remove avoidEvents from example HeatPump_BrineWater.mo and update example HeatPump_Events.mo
remove the '''translate''' from unittest of Boilers and heat pump and update unit test of HeatPump_BrineWater.mos
Merge pull request #160 from open-ideas/issue78_scalingHeatPump

correct scaling of heat pump and error caused by avoidEvent.
Merge branch 'issue47_AllowMoreEvents' of https://github.com/saroele/IDEAS into Annex60

Conflicts:
	IDEAS/Media/Air.mo
replace the Hyst_Var_Cooling.mo and _Heating by a general hysteresis valid for both cases and with conditional inputs.
add unit test for HysteresisRelease_Cooling.mos and _Heating
add filter for on/off signal
Deleting obsolete and double defined Air.mo (replaced by package Air).  Not clear why I have to do this again, commited this before.
Different changes in the documentation, and ensuring that the new release control is used in the heat pump and boiler's heatsource models.

This reverts commit a3f2f82d8a15df9c2441a6f15d543c918413fb8d.
add on-off control to PumpExample.mo
make the filter of on-off signal conditional too to avoid overhead.

@Mathadon I would rather not connect realExpression1 to a filter. It would cause multiple filtering. I connected instead the on_internal to a filter and made the filter also conditional (only if use_onOffSignal). I will close this issue as I updated the code according to your comments.
correct boolean parameter in solarShading (now controlled instead of controled).
