Pointer and Reference Expressions

[RyanJeong]

When referring to a pointer or reference (variable declarations or definitions, arguments, return types, template parameters, etc), you may place the space before or after the asterisk/ampersand. In the trailing-space style, the space is elided in some cases (template parameters, etc).

// These are fine, space preceding.
char *c;
const std::string &str;
int *GetPointer();
std::vector<char *>

// These are fine, space following (or elided).
char* c;
const std::string& str;
int* GetPointer();
std::vector<char*>  // Note no space between '*' and '>'

I prefer the first way because it allows me to maintain consistency with C-style code. So I need to apply the first way to this repo.
