ViSigrid-class: Class 'ViSigrid'
In ViSiElse: A Visual Tool for Behavior Analysis over Time

Class ViSigrid defines the structure of the process to be plotted.

MATp: A "dgCMatrix". It stores the grid for all punctual actions in the book.
MATpsup: A "dgCMatrix". It stores the grid for all punctual actions in the book corresponding to the supplementary times.
idsup: A "vector" It stores individuals id having supplementary times.
colvect: A "matrix" Matrix with colors to use.
L: A "data.frame" It stores the data corresponding to long actions having a showorder.
idsort: A "matrix" For all long actions, it stores the order of individuals in which each actions will be plot.
BZL: A "dgCMatrix" It stores black zones for long actions, calculated for each individuals.
Lsup: A "data.frame" for the long actions having a showorder and supplementary times defined, it stores the data corresponding to those actions.
book: A "ViSibook" it stores the structure of the grid for the plot.
group: A "factor" it stores the group for the each individuals.
vect_tps: A "vector" it stores the times vector mapping the grid.
informers: A "matrix" It stores the statistics (mean, median or NULL) by actions.
testsP: A "vector" Results of tests p.value<threshold.test.
parameters: A "list". It stores the parameters put in the visielse function.
