Detailed Description
Generic class for parameters of refinable objects.
These must be continuous.
- Todo:
: define parameters using equations between parameters.
: for complex objects with lots of parameters, give the possibility to define vectors of parameters, all with the same properties, to reduce memory usage.

Constructor.
- name: the name of the parameter
- refPar: the address of the refined parameter
- min,max: the minimum & maximum value for this parameter. Only used
- if the parameter is limited.
- type: the type (category) of refinable parameter. This is used to (de)activate
- groups of parameters.
- derivMode: to compute numerical (partial) derivatives, the step used is either
- an absolute (fixed) value, or it can be proportionnal to the current value of the parameter.
- hasLimits: if true, then the parameter cannot exceed its limits.
- isFixed: if true, the parameter cannot be refined.
- isUsed: if false, then the parameter does not affect in any way the refined object,
- and thus is simply ignored and should never appear to the user.
- isPeriodic: if true, then when the parameter exceeds one of its limits, it is
- shifted by the period (=max-min), in order to be back to the allowed [min,max] range.
- humanScale:this is the scale which should be used to display the value to the
- end program user. This is mostly used for angles: the values are stored in radians, so that a scale equal to 180/pi must be used for a 'human-understandable' value. Use the RefinablePar::HumanValue() in order to get this value. By default it is equal to 1.0 (no scaling required).

| void ObjCryst::RefinablePar::Mutate | ( | const REAL | mutateValue | ) |
Add the given amount to the parameter current value.

| void ObjCryst::RefinablePar::MutateTo | ( | const REAL | newValue | ) |
Change the current value to the given one.
If the limit is hit, then set to the limit (unless the pameter is periodic, then shift by the period amount back to allowed values).
