.medianSpecGrp: Rescale respective to specific group
Description
This function allows to rescale data 'x' so that specific group 'grpNum' gets normalized to predefined value 'grpVal'.
In normal case x will be multiplied by 'grpVal' and devided by value obtained from 'grpNum'.
If summary of 'grpNum-positions' or 'grpVal' is 0, then grpVal will be attained by subtraction of summary & adding grpVal
