ENH: Exposing jqplot options to select marker size and line width in …
…qMRMLChartView
Exposing two new options for jqplot: 'size' allows to select the size of the marker, and 'lineWidth' allows to select the width of a line. This allows to change these options when using qMRMLChartView. Both properties should be set with a string containing an integer (greater than 0).
