/**

 * Implements a tab to modify attributes of an arrow decorator (size,

 * arrow sharpnss, symbol, number of symbols to draw in the same line and options

 * for flip and rotate the arrow)which allows the user to insert a symbol in the

 * line (for example an arrow to specify its orientation)and to modify it.

 *

 * <p>

 * This tab is used several times in different places in our applicattion .For

 * this reason, in order to avoid the repetition of code, this class has been

 * created (instead of treat it like a simple tab). With this solution, the user

 * only has to refer it to use it (and do not need to create a tab and fill it again

 * and so on).
