Maxima functions for linear differential equations

Hello,

Below I am attaching a file for the solutions of various linear 
differential equations related to the Bessel functions. 
The functions solve the modified Bessel equation, the Airy equation,
the Scorer equation and the Lommel/Struve/Anger-Weber equations. 
These equations are not integrated by ode2 or contrib_ode (but some of
them can be integrated  by odelin.lisp). 
I have tried to use existing maxima notations for the results, i.e. the
struve function is represented as hstruve[n](x) as in the specint
package. However, the order of the parameters in slommel is not
indicated in the specint documentation, so there could be some
incompatibility. Also, the scorer_gi, anger_j, weber_e functions
are not defined anywhere in maxima. 

Another function is solving the Lam? equation in polynomial form. 

I hope these maxima functions can be polished and included in a future
release. 

Best,

E. Orignac
