TAChart

TAChart is a charting LGPL component for Lazarus (TeeChart LineSerie like).
It contains the functions I need for the TeleAuto project but I'll improve
it in the future.

Its main caracteristics are :

* Unlimited number of graphs

* Graph legend
* Graph title
* Axis labels

* Reticule or vertical reticule with point measure
* Line drawing between points
* Point drawing on each point
* Different point shapes (square,circle, cross, diagonal cross and star)
* Color each point and line
* Mirror on X axis
* Auto or manual graph limits
