Message:

update core_shell_cylinder docs to address #1030

Updated docs to point out the core_shell_cylinder includes end caps.
Point users to core_shell_bicelle if they want a core_shell_cylinder
without end caps (by setting face thickness to zero) — setting face
thickness to zero was tested and verified that setting that parameter to
zero does not cause a problem

    55The output of the 2D scattering intensity function for oriented core-shell 
    66cylinders is given by (Kline, 2006 [#kline]_). The form factor is normalized 
    7 by the particle volume. 
     7by the particle volume. Note that in this model the shell envelops the entire 
     8core so that besides a "sleeve" around the core, the shell also provides two 
     9flat end caps of thickness = shell thickness. In other words the length of the 
     10total cyclinder is the length of the core cylinder plus twice the thickness of 
     11the shell. If no end caps are desired one should use the 
     12:ref:`core-shell-bicelle` and set the thickness of the end caps (in this case 
     13the "thick_face") to zero.
