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

 r917d975 The output of the 2D scattering intensity function for oriented core-shell cylinders is given by (Kline, 2006 [#kline]_). The form factor is normalized by the particle volume. by the particle volume. Note that in this model the shell envelops the entire core so that besides a "sleeve" around the core, the shell also provides two flat end caps of thickness = shell thickness. In other words the length of the total cyclinder is the length of the core cylinder plus twice the thickness of the shell. If no end caps are desired one should use the :ref:core-shell-bicelle and set the thickness of the end caps (in this case the "thick_face") to zero. .. math:: and $\alpha$ is the angle between the axis of the cylinder and $\vec q$, $V_s$ is the volume of the outer shell (i.e. the total volume, including the shell), $V_c$ is the volume of the core, $L$ is the length of the core, $V_s$ is the total volume (i.e. including both the core and the outer shell), $V_c$ is the volume of the core, $L$ is the length of the core, $R$ is the radius of the core, $T$ is the thickness of the shell, $\rho_c$ is the scattering length density of the core, $\rho_s$ is the scattering
