DependendSymbol extents Symbol by modifying the == operator to allow two instances to be equal. Two DependendSymbols are equal if they have the same shape, the same arguments and one of them has an unspecified spatial dimension or the spatial dimension is identical.

Example:

 u1=Symbol(shape=(3,4),dim=2,args=[4.])
 u2=Symbol(shape=(3,4),dim=2,args=[4.])
 print u1==u2
 False

but:

 u1=DependendSymbol(shape=(3,4),dim=2,args=[4.])
 u2=DependendSymbol(shape=(3,4),dim=2,args=[4.])
 u3=DependendSymbol(shape=(2,),dim=2,args=[4.])
 print u1==u2, u1==u3
 True False
