*
* Component: PreMonitor_nD
*
* %Identification
* Written by: <a href="mailto:farhi@ill.fr">Emmanuel Farhi</a>
* Modified for xrays by Erik B Knudsen
* Date: 01st Nov 2011.
* Origin: <a href="http://www.ill.fr">ILL (France)</a>
* Release: McXtrace 1.1
*
* Xray parameters spatial cross-correlation monitor.
*
* %Description
* Photon parameters are stored when entering in the PreMonitor.
* If this photon then reaches the associated Monitor_nD, this latter
* component measures the previously stored parameters. This enables to study
* correlations between a given parameter in one place of the instrument
* and an other detection position in the instrument.
*
* <b>EXAMPLES:</b>
* Here follows a Phase-Space correlation diagram detector
* (used for guides for instance)
*
* MyPreMonitor = PreMonitor_nD(
* monitor_comp = MyMonitor)
*
* ...some optics....
*
* MyMonitor = Monitor_nD(
* xwidth = 0.1, yheight = 0.1,
* options = "hdiv x, auto, use premonitor");
*
* %Parameters
* INPUT PARAMETERS:
*
* monitor_comp: name of the associated Monitor_nD where the detection should take place [no quotes]
*
* CALCULATED PARAMETERS:
