Fixed ghost particles fields interpolation.

In order to conveniently extend the flow fields we need to know the mirrored values. Also the Shepard values should be recomputed taking into account the mirrored position.

Parameters

imove	Moving flags. imove > 0 for regular fluid particles. imove = 0 for sensors. imove < 0 for boundary elements/particles.
r	Position \( \mathbf{r} \).
normal	Normal \( \mathbf{n} \).
m	Mass \( m \).
rho	Density \( \rho \).
p	Pressure \( p \).
u	Velocity \( \mathbf{u} \).
gp_rho	Interpolated density in the mirrored position \( \rho \).
gp_p	Interpolated pressure in the mirrored position \( p \).
gp_u	Interpolated velocity in the mirrored position \( \mathbf{u} \).
shepard	Shepard term \( \gamma(\mathbf{x}) = \int_{\Omega} W(\mathbf{y} - \mathbf{x}) \mathrm{d}\mathbf{x} \).
icell	Cell where each particle is located.
gp_icell	Cell where each mirrored ghost particle is located.
ihoc	Head of chain for each cell (first particle found).
N	Number of particles.
n_cells	Number of cells in each direction
