Detailed Description

template<unsigned int dim, typename T>
class Ghost< dim, T >

it indicate the ghost extension

Ghost margins for each dimensions (p1 negative part) (p2 positive part) ^ p2[1] | | +-—+-—+ | | | | p1[0]<--—+ +-—> p2[0] | | | | +-—+-—+ | v p1[1]

\warning p1[0] and p1[1] must be negative hile p2[1] and p2[0] must be positive
