Detailed Description

CItemIndexForLoading holds all occurrences of one index item (token, morph. pattern...) on the index stage.

There are only two members: m_pCurrOccurs and m_IndexItemOffset. Member m_pCurrOccurs is a pointer to the vector of occurrences of an indexed string. We use here pointers because we are going to create vector<CItemIndexForLoading>, and pointers can help us to avoid copying all occurrences each time when an item is inserted to vector<CItemIndexForLoading>. Member m_IndexItemOffset is an reference to CIndexSetForLoadingStage::m_StringBuffer
