Class Description

                                                                      
 TDrawInfo                                                            
                                                                      
 Class that parses all parameters for TTree::Draw().                  
 See TTree::Draw() for the format description.                        
                                                                      

 Constructor - cleans all the class variables.

 Destructor.

 Resets all the variables of the class.

 Parse expression [var1 [:var2 [:var3] ...]],
 number of variables cannot be greater than fgMaxDimension.
 A colon which is followed by (or that follows) another semicolon
 is not regarded as a separator.
 If there are more separating : than fgMaxDimension - 1 then
 all characters after (fgMaxDimension - 1)th colon is put into
 the last variable.
 fDimension := <number of variables>
 fVarExp[0] := <first variable string>
 fVarExp[1] := <second variable string>
 ..
 Returns kFALSE in case of an error.

 Syntax:
 [[+]name[(num1 [, [num2] ] [, [num3] ] ...)]]
 num's are floating point numbers
 sets the fileds fNoParameters, fParameterGiven, fParameters, fAdd, fName
 to apropriate values.
 Returns fKALSE in case of an error.

 Split variables and parse name and parameters in brackets.

 Check if options contain some data important for choosing the type of the
 drawn object.

 Parses parameters from TTree::Draw().
 varexp - Variable expression; see TTree::Draw()
 selection - selection expression; see TTree::Draw()
 option - Drawnig option; see TTree::Draw

 Returns apropriate TSelector class name for proof for the object that is to be drawn
 assumes that Parse() method has been called before.

 returns *num*-th parameter from brackets in the expression
 in case of an error (wrong number) returns 0.0
 num - number of parameter (counted from 0)

 num - parameter number
 def - default value of the parameter
 returns the value of *num*-th parameter from the brackets in the variable expression
 if the parameter of that number wasn't specified returns *def*.

 returns kTRUE if the *num*-th parameter was specified
 otherwise returns fFALSE
 in case of an error (wrong num) prints an error message and
 returns kFALSE.

 Returns the *num*-th variable string
 in case of an error prints an error message and returns an empty string.

 Returns the variable string, i.e. [var1[:var2[:var2[:var4]]]].
